69-611 12.0mm Dia. x 30.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm
The 69-611 is a Plano-Convex spherical lens, characterized by its circular base shape and a diameter of 12.0mm. This lens is designed with a long focal length of 30.0mm, making it suitable for a variety of applications that require precise focusing. The lens is fabricated from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including high transparency and low dispersion.
The lens features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). The curvature of the convex side is defined by a radius of 15.5mm. This geometry allows for efficient light gathering and focusing, making it ideal for use in laser applications.
The 69-611 lens is coated with Edmund Optics' Laser V-Coat 1064, a broadband anti-reflection coating specifically designed for use with 1064nm wavelengths. This coating reduces surface reflections, enhancing the lens's transmission efficiency and overall performance.
The lens has a thickness of 1.79mm at the edge and 3.0mm at the center. The back focal length (BFL) is 28.02mm, and the effective focal length (EFL) is 30mm. The lens is currently in stock and available for immediate purchase from Edmund Optics.
